These hole saws do a great job

This set is fantastic. I live in a rural area and getting any of the trades to show up, electricians included, is nearly impossible.I used this to put several holes in my generator transfer switch. 2" is the max size with a 2.5" bit. These bite are very expensive indvidually. This set paid for itself already. Cuts through panels with no issues. These would probably last 50+ cuts through regular panel steel no problem. Heavier stuff, well it probably won't last.

This has just about every size I need to do panel upgrades in residential Properties

So far, so good. Had it for a while but not used much. Just be sure to use cutting oil when cutting holes into metal enclosures to extend life of bits.
